Today, aftermarket associations, carmaker associations, parts manufacturers and suppliers are working together to solve a myriad of complex issues with the original core issue hanging over their head: money.
The 2004-2009 Mazda3 is based on the Ford global C1 platform, shared with the European Ford Focus and Volvo S40. Nothing is really groundbreaking about the brake system, but not paying attention to the details can end in a post-brake-job comeback.
I have a friend who is always telling me about his latest diagnostic misadventures. The phrase he uses a lot starts with “I think,” followed by a patchwork tale of myths, stuff he read online and personal experience. He often theorizes about what is going on inside of the combustion chamber and relates it to a random MIL code.
When the brake pad’s friction surface is not in harmony with the caliper and rotor, the result is usually noise. But, brake pad manufacturers have some tricks to prevent this problem or at least shift it outside of the range of human hearing.
To determine if a vibration is vehicle- or engine-speed related, the easiest thing to do is slip the transmission into neutral and let the vehicle coast when the vibration is most noticeable. If the vibration continues, then the vibration is vehicle-speed related. Likewise, if the vibration subsides, the vibration is engine-speed related.
More automotive manufacturers today are opting for the use of the continuously variable damping system called Continuous Damping Control (CDC) in their vehicles. It permanently monitors “influencing” factors, such as the road condition, load, vehicle body acceleration and driver’s actions.
Troubleshooting an automatic transmission can be one of the most intimidating diagnostic procedures at a shop. The first reaction is typically, “We don’t do that type of work,” but there is profit in performing drivetrain diagnostics and “in-the-car” repairs.
On the hubs for 2005-2014 Subaru Legacy and Outback applications, a speed sensor mounts into the knuckle. It’s exposed end extends out behind the bearing to capture pulses from an encoder ring on the back of the bearing.
